The best way to control sediment erosion is to limit the number of areas that you work on. Work only on the necessary areas and avoid areas that have topsoil in place. Try and maintain natural vegetation as much as possible as it is vital sediment erosion protection. The vegetation keeps soil in place with their roots, and uprooting them will cause the soil to become loose and sediment erosion will occur. Divide your construction project into phases. Using this method, the amount of erosion and sedimentation problems can be minimized as smaller areas are much easier to manage. It is important to have designated areas laid out for any runoff water. You can install a sediment trap in this area and this fill trap the runoff water containing sediment. You can redirect the water using ditches placed strategically along the up-slope of a construction site. The best way to prevent sediment erosion is to stabilize the soil. Soil is best stabilized by the roots of the natural vegetation growing there, but if there is no natural vegetation you can use methods like seeding, mulch, blankets, and wool binders. These methods can either be permanent or temporary but implementing a permanent solution would be more beneficial to everyone. Erosion on slopes can be controlled using a variety of options. The option chosen will depend on the degree of inclination of the slope in question. Some options to prevent erosion on slopes are: silt fence, fiber rolls, geo-textile turf blankets and mats. Storm inlet protection is vital in order to prevent sediment erosion. Protecting a storm drain inlet from erosion and sediment can be achieved by using the following methods: silt fence, rock-filled bags, block and gravel. The kind of protection you use depends entirely on what type of drain it is, how large the drain’s opening is, and how big the flow it’s expected to receive is. Establishing and securing a clean perimeter is an easy way to prevent sediment erosion. You can create a clean perimeter by implementing a temporary silt fence barrier. If this barrier is properly installed and trenched into the ground, it will provide lateral resistance. Sediment flowing down with storm-water will then be caught by the perimeter fence. This method only works in small areas and it is not a good idea to try and implement this method in large areas. Most sediment related problems can be solved by installing sediment traps or basins. Sediment traps or basins will lower the amount of runoff water allowing sediment to settle. This trap should have the capacity to store two years’ worth of storm water. The most important thing you can do to prevent sediment erosion is to continuously inspect the systems you have already implemented and improve upon them. New sediment erosion prevention techniques should be tried and tested until you find the method that works best for you.
